Different products, different salts of acids, different %'sSpray too much, grass will start to die, but does grow back.

When I wanted to get my lawn in better shape, what worked good for me was:1) Spray with a Weed-N-Feed using a garden hose and spray the whole lawn.This gave good coverage and got rid of most weeds.Repeat 2 Weeks later.

2) Buy some weed-killer in concentrate form and spot treat the tougher weeds using a pump sprayer.

It's a balancing act between weed control and using minimum amount of chemicals.

Exactly what kind of weed is it ? ? ?Probably what someone posted in that photo (or of the same sub-species).

My Brother has a walking path in his back-yard.He noticed that the Daiseys along the 'sides' of the path were growing shorter than what was growing in the tall grass.I would guess that the shorter ones were not competing for sun-light and knew they didn't have to grow so tall.Same flowers, some what different look.

The soil shown by the O.P. looks like clay. So poor soil fits the bill there.

I've seen similar plantation develop in my concrete driveway cracks. What's really bad this year here in Lower Michigan is quackgrass. I've gotten more this year, than in the past several years.

We are also looking at another summer where the nut trees are not dropping at all. This is the 3rd time in the past four years. Our neighborhood squirrel population is really sparse these days. In normal times, I would count 5-10 squirrels right outside my living room window. Now I'm staring at only (1, as I type this response.

I was spraying Tzone SE on some wild violets weeds and had a little left and sprayed some on the red sorrel and over night the area I sprayed looked well on the way to dying. The wild violets were not effected the same way. Hopefully in a few days the wild violets will die also.
